Whenever you enter a new POS Session record, it will be given a unique identifying number based on a sequential number series.

You can have more than one sequential number series running at the same time, or at different times. For example, you may want to use different sequences to represent different departments, or you may want to use different sequences to represent different fiscal or calendar years.

The Number Series - POS Sessions setting allows you to take advantage of this feature. Here you can define the number sequences that you would like to use with POS Sessions.

To open the Number Series - POS Sessions setting, ensure you are in the Point of Sales module and double-click (Windows/Mac OS X) or tap (iOS/Android) 'Number Series - POS Sessions' in the 'Settings' list. The following window will appear:

Enter each new Number Series on the first blank line. The sequences that you enter should not overlap. The N/L field common to all Number Series settings is not used with POS Sessions.

When the setting is complete, click the [Save] button (Windows/Mac OS X) or tap √ (iOS/Android) in the Button Bar to save the changes. To close the window without saving changes, click the close box (Windows/Mac OS X) or tap < (iOS/Android).

When you enter a POS Session record, the next number in the first valid Number Series entered to this setting will be used as a default. You are free to change to the first unused number in any other valid Number Series. However, you will usually create POS Balance records using the "Open Session" and "Close Session" POS Buttons in the POS Invoice and/or Bar Tab windows or via the 'Cash Up' report and Maintenance function. There will be no opportunity to change the number in these records, so a typical use for this setting will be to create separate number sequences for each year.

If you leave the Number Series - POS Sessions setting empty, POS Session Numbers will all be taken from the same sequence, starting at 1 and continuing consecutively. If you want to start from another number, simply specify it in a new POS Session record before saving.

If you have any tills that use live-sync connections to the server, you must not leave the Number Series - POS Sessions setting empty. You must also use the Synchronised Number Series setting to define separate number sequences for each live-sync till, before connecting any of those tills to the server. Please refer here for details.
